Kyoto team develops new cathode material for high-energy-density rechargeable magnesium batteries

Green Car Congress

A team of researchers from Kyoto University has demonstrated ion-exchanged MgFeSiO 4 as a feasible cathode material for use in high-energy-density rechargeable magnesium batteries. In addition to the high capacity, the relatively high negative reduction potential of magnesium metal can provide high energy density. Orikasa et al.

2024 Chery Omoda E5 review: is it too flawed to challenge the BYD Atto 3?

EV Central

Range of 430km trumps entry-level Chinese rivals, using a 61.1kWh battery and with energy use of 15.5kWh/100km. DC recharge time is 30 minutes from 30-80 per cent charge, Chery choosing not to reveal how long it would take from 10 per cent charge, as is the norm. Claimed performance is 7.6 seconds to 100km/h.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

Photo-illustration: Max-o-matic; photo source: M&N/Alamy Some operators of early direct-current power plants at the turn of the 20th century solved the problem of uneven power output from their generators by employing large banks of rechargeable lead-acid batteries, which served as a kind of buffer to balance the flow of electrons.

Clearing the roadblocks to electrification of heavy-duty trucks

Charged EVs

If we’re going to hit the numbers we need to hit for fleet adoption, we need as many places for those vehicles to recharge as possible. Those guys don’t have the wherewithal to finance a battery-electric truck that costs twice as much as a diesel truck, and they’re usually buying third- or fourth-owner diesels anyway, that are super-cheap.
